Grounding Function
The grounding function increases the resistance against disturbances from electro-
magnetic interferences. Some components in the I/O system have a carrier rail
contact that dissipates electro-magnetic disturbances to the carrier rail.

DANGER
Ensure sufficient grounding is provided!
You must take care to ensure the direct electrical connection between the carrier
rail contact and the carrier rail.
The carrier rail must be grounded.
For information on carrier rail properties, please see chapter “
